3) The equation of the linear model would be y = 7.5x+60.

4) If Adam studies for 6 hours then his score would be 88.

What is the Linear equation?

An algebraic equation with only a constant and a first-order (linear) term is said to be linear if it has the formula y = mx + b, where m is the slope and b is the y-intercept. The above is occasionally referred to as a "linear equation with two variables," where y and x are the variables.

y = mx + c

where m denotes the slope.

The y-intercept is represented by the constant c. (Where x is zero)

In our instance, y-intercept equals 60.

The line's equation will therefore be:

y = mx + 60

y = mx + 60

There are given the line's coordinates (4, 90). These considerations will thus satisfy the equation.

90 = 4*m + 60

4.m = 30 m = 7.5 m = 7.5 y = 7.5x + 60 y = 7.5 * 6 + 60 y = 45 + 60 y = 105 is

y = 7.5x + 60.

If Adam's study for 6 hours then his score would be

y = 7.5x + 60.

y = 7.5(6) + 60

y = 105

Hence,

3) The equation of the linear model would be y = 7.5x+60.

4) If Adam studies for 6 hours then his score would be 88.

The center of the circle is (3 , -2) and the radius is 4 then the equation of circle is (x)² + (y)²-6x+4y = 3

What is a circle?

The circle is defined as the locus of the point traces around a fixed point called as the center and is equidistant from the outer trace.

All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.

The equation of the circle is,

( x - h )² + ( y - k )² = r²

(x-3)² + (y+2)² = 16

(x)² + (y)²-6x+9 +4y+4 = 16

The linear speed of the vehicle In miles per hour is 19.04 miles per hour

Angular speed is the time rate at which an object rotates, or revolves, about an axis, or at which the angular displacement between two bodies changes. In the figure, this displacement is represented by the angle θ between a line on one body and a line on the other.

The relationship between angular and linear speed is v = wr

where w= angular speed

v = linear speed

and r is the radius

1 inch = 1.578×10^-5

r = 32/2 = 16 inches = 16×1.578×10^-5

= 25.25×10^-5 = 2.5×10^-4miles

1 revolution = 2π = 6.28

800 revolution = 6.28× 800 = 5024

1 minutes = 1/60

800rev/minutes = 5024×60= 301440 rad/hour

v = wr

v = 301440 × 1.578 × 10^-5 = 4.76 miles per hour

Step-by-step explanation:

Using the normal distribution and the central limit theorem, considering that this is a sample proportion, as we are dealing with percentages, it is found that there is a 0.1562 = 15.62% probability of getting less than 50% Democrats in a random sample of size 100.

Normal Probability Distribution

In a normal distribution with mean  and standard deviation , the z-score of a measure X

It measures how many standard deviations the measure is from the mean.  

After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

By the Central Limit Theorem, the sampling distribution of sample proportions of a proportion p in a sample of size n has mean  and standard deviation .

In this problem:

55% of the registered voters are Democrats, hence .

A sample of size 100 is taken, hence

The mean and the standard deviation of the sampling distribution of sample proportions

The probability of getting less than 50% Democrats in a random sample of size 100 is the p-value of Z when X = 0.5, hence:

By the Central Limit Theorem

Answer:4x+3

Step-by-step explanation:

Given the following in the question if:

Volume of the box= 4x3+19x2+12z

Height of the box= x

width of the box =?

we have to find the width of the box, so as we know that

box is in the shape of cuboid, so

Volume of the cuboid = length * width * height

4x3+9x2+12x   =   x+4* width * x

width = 4x3+9x2+2x/x2+4x

we have to use long division method for this algebraic expression to divide and find width of the box.

we get width= 4x+3

Hence, the width of the box which in the shape of cuboid is 4x+3

To calculate how much should be placed in an account now to have $21,200 cash for a new car 7 years from now, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = future value (amount of money after t years)

P = present value (amount of money now)

r = annual interest rate (as a decimal)

n = number of times the interest is compounded per year

t = number of years

In this case, we have:

A = $21,200

r = 0.064 (6.4% as a decimal)

t = 7

n = 1 (the interest is compounded annually)

So, we can solve for P:

P = A / (1 + r/n)^(nt)

P = $21,200 / (1 + 0.064)^(7)

P = $15,093.35

Therefore, the person should place $15,093.35 in an account now to have $21,200 cash for a new car 7 years from now, at an annual interest rate of 6.4%.

The dealerships will each have sold 23 cars in 1 day.

The first step is to form a linear equation that represents the number of cars that are sold by the dealerships. A linear equation is an equation that has a single variable that is raised to the power of one.

The form of a linear equation that represents the total cars sold by the dealership is:

Total cars sold = cars already sold + (number of cars sold per day x number of days)

Total cars sold by Clarksville Cars= 15 + (8 x d)

= 15 + 8d

Total cars sold by Robinson's Autos = 13 + (10 x d)

= 13 + 10d

When the two dealerships are tied, the two above functions would be equal:

13 + 10d= 15 + 8d

In order to determine the value of d, take the following steps:

Combine and add similar terms:

10d - 8d = 15 - 13

2d = 2

Divide both sides of the equation by 2

d = 2 / 2

The equations are 100x + 80y = 25600 and 50x + 160y = 18200.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Let x be the cost of a quail and y be the cost of a rabbit bought by the business lady.

Given that a business lady bought 100 quails and 80 rabbits for sh 25600.

100x + 80y = 25600

If she bought twice as many rabbits, number of rabbits = 80 × 2 = 160.

If she bought half as many quails, number of quails = 100/2 = 50

The equation is then,

50x + 160y = 25600 - 7400

50x + 160y = 18200

Sampling variation will have more impact on confidence interval but it is not accounted for by the margin of error.

What is Sampling variation?

The term "sampling variance" describes how much a sample estimate (a statistic) is likely to fluctuate from sample to sample due to the unique nature of each sample.

Sample Sizes and Variability are the factors which lead to sampling variation. As and when the sample size is changed i.e. either increased or decreased, the variability of samples fluctuates.

Since, Sam runs a large chain of car repair shops, this means he has large number of employees.

But his sample size is only of 10 employees whom he asks about their billable hours from which he constructs a 95% confidence interval for the true mean number of billable hours for all employees in the company.

Since, sampling variation is greatly affected by the sample size and variability, therefore it will have more impact on confidence interval.

Let the bill after the tax plus tip will be a and the bill after tax be b,

Therefore,

Event A: "at least one die is a 3" is not mutually exclusive with Event B: "at least one die is a 6" or Event C: "the sum is 11"

Event A and Event B are mutually exclusive because when one of the die is a 6, the other die cannot be a 3 and vice versa.

Event A and Event C are not mutually exclusive because there are some outcomes where at least one die is a 3 and the sum is 11. For example (3,8), (4,7) and (6,5) are all outcomes where at least one die is 3 and the sum is 11.

Event B and Event C are not mutually exclusive because there are outcomes where at least one die is a 6 and the sum is 11. For example (5,6) and (6,5) are both outcomes where at least one die is a 6 and the sum is 11.
